@Trojan404 Yeah, try to separate the responsibilities a bit better.

Trojan404

@EBrown That's what I've been working the last day on - I ended up remigrating my database with new fields to try and remove the need to do substr but this will result in needing to either pass more info or do another db query :P

Vogel612

aaand they're back up.

Trojan404

Don't worry, I've taken the heat before. Only reason I'm in PHP is because my professor pushed it for 3 years. He's under the impression that it is getting much better and that it will become a popular language. Which he's not completely wrong. It is much better, but it's going to have a very hard time getting a popular rep because it's the newbie language

EBrown

@pacmaninbw I like websites, I hate PHP. Lol I do ASP.NET all day every day.

Vogel612

N3buchadnezzar

@Trojan404 What are the serious alternatives to PHP?

pacmaninbw

@N3buchadnezzar python and perl

Trojan404

@N3buchadnezzar Like @EBrown said, ASP.NET. Not a whole lot of common and heavily pushed languages beyond that tho. Python Perl C# etc but .NET is the best one from what I can see

EBrown

@N3buchadnezzar Java, Python, Ruby, Perl, ASP.NET with C# or VB.NET

Vogel612

EBrown

@pacmaninbw Yeah, and Tomcat.

Trojan404

@N3buchadnezzar It's the nicest for website integration because it started out as a template language

EBrown

15:22

@N3buchadnezzar PHP is easy and simple.

Which is why it's so popular.

It's easy to learn, because it does a lot of the hard stuff for you.

A: A receptive map queue

The auth token is weird. Your class can't protect itself against reflection as far as I'm aware, so all this is doing is covering up a bad design. From the documentation I can sort of see it's supposed to guarantee thread safety - I don't understand why you'd go to such lengths; there are better ...

@Phrancis well

Set<PlayerCharacter> charactersToProcess = playersByTick.extractAllOnOrBefore(currentTick);
for(PlayerCharacter pc : charactersToProcess) {
    try(AutoLock pclock = pc.getLock().write()) {
        simulator.bringGameStateToCurrent(pc);
    } catch(Exception pokemon) {
        log("error in processing " + pc.getName() + " tick " + currentTick, e);
    }
}

e is undefined.

Phrancis

It looks like they just fixed that in most recent edit

Pimgd

Yeah that's fine

the rest of the code, I'm sure it works, but it's just... wtf...

It screams pre-mature optimization to me

and then explains only the really deep parts

like the author was talking to themselves or something in the comments

It wants to be thread safe but it also has to be performant so it throws the thread safety out of the window and instead guarantees thread safety by use of a password object

Phrancis

Sounds strange

Pimgd

it spends 8 lines of code and comments to save 1 object instantiation

because oooh performance

and then it doesn't even work for the described use case!

if a value can only have one key, then two keys cannot have the same value.

Yet it's supposedly a tick, player to move map.

except "active users get processed every 5 ticks"

so obviously that restricts you to 5 active users

1, a
2, b
3, c
4, d
5, e
6, a
...

but then in the question again "I tried it with a million entries" which is great except... it can't really do more than 5?

I just hope I'm missing something obvious here or that I just completely misread something

hey, good idea :)

Phrancis

Welcome @corsiKa :)

Pimgd

ello

scroll up a bit to see me ranting

corsiKa

19:24

no worries

i do the same when i look at other people's code - why i don't develop professionally anymore haha

so about the Auth Token - a better approach would be for me to have some kind of extractor class

a factory method returns the extractor, which can access the queue's private (protected/whatever) methods

i make the queue available to the producer threads, and the consumer threads can work among themselves to synchronize access

i haven't had time timplement that, and, well, the auth token was easy :)

Pimgd

Either you're thread safe via synchronization or you ... don't pass the object where it's not supposed to go

corsiKa

but i have to pass the object to the producer threads so they can add those to the queue to be processed

Pimgd

Or, and this is pretty weird, but, you trust that code will not be malicious

corsiKa

that's true, i could just do that

i do that elsewhere in the app as well

Pimgd

Another idea is that you provide an interface

not the implementation

and the interface doesn't have the hidden methods

corsiKa

19:26

I actually really like that idea

just made a note of that - i think the interface, which producers only see the producer-friendly interface, is a much better idea and should be a cakewalk to implement

hubot

I corrected code in my question codereview.stackexchange.com/questions/132279/…

Pimgd

@hubot do the testcases still fail?

If not, why is this still in the question text?

corsiKa

so clear wait list - you're right, could be named better - the waiting list exists so producers can dump items to process without blocking other producers or the consumer - perhaps the consumer might not get to it this tick, but that isn't a problem - we start at the beginning of the keys queue when we extract so if it should have gone this tick, no worries it goes next tick

hubot

19:30

I edited to OK

corsiKa

so renaming that to processPendingAdds or something might be more appropriate

hubot

But Visual Studio crashes me

corsiKa

Unfortunately, that isn't really descriptive either because this queue doesn't do any processing - it sorts and queues up items to be processed by a consumer

Pimgd

@corsiKa processQueue does not mean the queue does the processing, it means the queue is processed.

corsiKa

fair enough

about that empty HashSet, that wasn't premature - that one change increased the speed of the overall game loop by over 10% - i'm on barebones hardware (shoestring budget) so that was quite a bit of improvement

Pimgd

19:34

Now that's information I'd add to the comments

corsiKa

but you were right to flag it, because it does appear unnecessarily overcomplicated

Another comment I need is what you pointed out - why do we check if it's empty if the loop is not empty

There was a reason at one point - that might be an artifact from before I added the auth token

Pimgd

updated answer with minor improvement

corsiKa

yeah that must have been it - from the time when i was planning to have multiple consumer threads that didn't externally synchronize - but now they need to be synchronized (or just have one)

Pimgd

but, about the performance...

        Set<V> set = map.putIfAbsent(p.k, nextEmptySet);
        if(set == null) {
            set = nextEmptySet;
            nextEmptySet = new HashSet<>();
            keys.add(p.k);
        }

and

        Set<V> set = map.get(p.k);
        if(set == null) {
            set = new HashSet<>();
            map.put(p.k, set);
            keys.add(p.k);
        }

That's... 10% slower?

Really?

corsiKa

yeah, it is

wait the get?

that's not what i did

Pimgd

19:41

but that's the same functional result, right?

corsiKa

i used put if absent with new HashSet<>()

should be, let me give that a run through the bm

Pimgd

The only thing different is that it will now replace null values, I think

corsiKa

that takes 14 seconds

original takes 8

probably because it does two lookups instead of one

one to get and one to put

yeah that's 8.9 there

hubot

merge these.

Hosch250

My two Roslyn quick fixes are in the latest preview release of VS: visualstudio.com/en-us/downloads/….

hubot

One iteration test: 1 sec, ten iteration test: 3 sec; both passed

so just K old = reverseLookup.put(p.v, p.k)?

Pimgd

@hubot your question says: "one iteration: 1 ms, "

@corsiKa yep

hubot

19:46

Should be sec

Pimgd

and remove the last reverseLookup.put line ofc

corsiKa

that did bring it down to 8.7s

Decision is left to the moderators. I have to go.

Pimgd

@corsiKa I think that you might want to make a constructor which takes a capacity / load factor

if map accesses are really that expensive

it's unlikely to reduce in size

@Atomic_alarm Ctrl-K is your friend

Pimgd

@syb0rg I tried CTRL+K here, it just goes lol no

corsiKa

@Pimgd So when you say "this map does not support two keys having the same value" - you see that it does now, right? That externally, the generic parameters are say, Integer and Player, but internally the map itself is Integer, Set<PlayerCharacter> - so many many players will be processeed on the same tick

Pimgd

@corsiKa private final Map<V, K> reverseLookup = new HashMap<>();

corsiKa

19:54

yes, but that's V,K not K,V

it's a reverse lookup

Pimgd

ReceptiveMapQueue<Integer, PlayerCharacter>

corsiKa

thus, each value can only have one key

Pimgd

thus Map<PlayerCharacter, Integer>...

corsiKa

yes - that essentially says "what tick do I play to process this player character?"

say pimgd is mapped to tick 100

it's tick 50 now

a new request comes in and says 'we need to process pimgd on tick 75 instead'

now, i can quickly find what tick you're in with reverseLookup.get(pimgd)

and find the set you're in with map.get(thatTickNumberIJustGot)

Pimgd

I guess that solves a lot of the confusion

corsiKa

19:56

remove you from that set and add you to the approriate set

Pimgd

that said, why don't you remove empty sets

if we're past tick 50 then ticks 1-50 can go, right?

corsiKa

right - and they do get removed

Pimgd

you're basically begging for OOM atm

Hosch250

Anyone want to review my Rubberduck PR's? My boss is on vacation.

corsiKa

in the extractAllOnOrBefore, I look through and Set<V> curSet = map.remove(cur);

Pimgd

19:57

I see

corsiKa

eventually, I'll get to the tick where you WERE going to get processed

and maybe i find an empty set there

generally a tick is a second, and no one will be processed more than an hour or so (currently, never know, I guess...)

Pimgd

I was wondering if there a way to figure out the number of ways to express an integer by adding up consecutive natural numbers. For example for $N=3$ there is one way to express it $1+2 = 3$ I have no idea where to start so any help would be appreciated

Pimgd

that's weird

corsiKa

yeah he went n*(n-1)/2

note (n-1) instead of (n+1) like the formula really is

Pimgd

yeah but does stack suck at math or ...?

corsiKa

so he got 199,990,000 instead of 200,010,000

var x = 0; for (var i = 1; i <= 20000; i++){ x += i; } x;

Vogel612

I daresay that's not really such a big issue...

Pimgd

console prints 200,010,000

stack sucks at math

Vogel612

Remonking btw.

corsiKa

he might be right though

because you're using <=

if you use < it's 199,990,000

Pimgd

...

lol

Pimgd

It has to add 20000 as well

Vogel612

Also ... pimping 5 hour old zombie kill of mine with currently 0 votes

corsiKa

yeah, and his words specifically say "20000 + 19999 + ..."

Pimgd

anyway, 1-9999 and 10001 - 19999 make 9999 pairs of 20000

corsiKa

he probably did the same thing you did and put < instead of <=

instead of using the formula

Pimgd

20:12

add 20000 to make 10000 pairs

add 10000 because it's in the middle and not used in a pair

Vogel612

You guys do know it wasn't 20k chars exactly??

Pimgd

= 200,010,000

@Vogel612 but the math in the post is wrong and I'm considering how to post this as a question somewhere that I can score many reps from

corsiKa

Yeah, that's how Gauss did it when he was elementary school pimgd

all about the benjamins

Vogel612

Also it's easier to have 10k pairs pf 20001

@pacmaninbw Nice avatar

Pimgd

Maybe mathematics stack exchange?

They'll probably shoot it down as too trivial

still, I has to complain somewhere

Vogel612

Trivial homework. Instaclose or downvotes into oblivion

Slow mobile typing is slow

corsiKa

put it on meta se?

Pimgd

Yes

... I'm scared for the downvotes because this is such nitpicking

corsiKa

hahaha - you only need a 2.5:1 ratio

Debatable spam? codereview.stackexchange.com/a/135428/27623

I'm wavering towards no

at the very least it discloses affiliation

so that's good
